Large-area polycrystalline -MoO3 thin films for IR photonics
Maria Cristina Larciprete, Daniele Ceneda, Chiyu Yang +8
In recent years, excitation of surface phonon polaritons (SPhPs) in van der Waals materials received wide attention from the nanophotonics community. Alpha-phase Molybdenum trioxid…
Polarimetric analysis of thermal emission from both reciprocal and nonreciprocal materials using fluctuational electrodynamics
Chiyu Yang, Wenshan Cai, Zhuomin M. Zhang
Coherent thermal emission for a given polarization has been observed in many metamaterials with micro/nanostructures. A complete description of the thermal emission requires the fu…
Spatial and doping effects on radiative recombination in thin-film near-field photonic energy converters
Dudong Feng, Shannon K. Yee, Zhuomin M. Zhang
Modeling radiative recombination is crucial to the analysis of photonic energy converters. In this work, a local radiative recombination coefficient is defined and derived based on…
A Novel Near-field Photonic Thermal Diode with hBN and InSb
Dudong Feng, Shannon K. Yee, Zhuomin M. Zhang
Similar to the diode in electronics, a thermal diode is a two-terminal device that allows heat to transfer easier in one direction (forward bias) than in the opposite direction (re…
Improved performance of a near-field thermophotovoltaic system by a back gapped reflector
Dudong Feng, Shannon K. Yee, Zhuomin M. Zhang
Various spectral control techniques can be applied to improve the performance of a thermophotovoltaic (TPV) system. For example, a back surface reflector (BSR) can improve the perf…
Spatial profiles of photon chemical potential in near-field thermophotovoltaic cells
Dudong Feng, Eric J. Tervo, Dragica Vasileska +3
Emitted photons stemming from the radiative recombination of electron-hole pairs carry chemical potential in radiative energy converters. This luminescent effect can substantially…
Coupled Charge and Radiation Transport Processes in Thermophotovoltaic and Thermoradiative Cells
William A. Callahan, Dudong Feng, Zhuomin M. Zhang +3
Accurate modeling of charge transport and both thermal and luminescent radiation is crucial to the understanding and design of radiative thermal energy converters. Charge carrier d…
Near-field radiative heat transfer between rough surfaces modeled using effective media with gradient distribution of dielectric function
Deyu Xu, Ahamed Bilal, Junming Zhao +2
Near-field radiative heat transfer (NFRHT) between rough surfaces, due to its widespread presence in engineering practice of near-field energy utilization, requires indepth studies…
Thermal radiation in systems of many dipoles
Eric J. Tervo, Mathieu Francoeur, Baratunde A. Cola +1
Systems of many nanoparticles or volume-discretized bodies exhibit collective radiative properties that could be used for enhanced, guided, or tunable thermal radiation. These are…
Photonic thermal conduction by infrared plasmonic resonators in semiconductor nanowires
Eric J. Tervo, Michael E. Gustafson, Zhuomin M. Zhang +2
Photons typically do not contribute to thermal transport within a solid due to their low energy density and tendency to be quickly absorbed. We propose a practical material system…
Validity of kinetic theory for radiative heat transfer in nanoparticle chains
Eric J. Tervo, Baratunde A. Cola, Zhuomin M. Zhang
In chains of closely-spaced nanoparticles supporting surface polaritons, near-field electromagnetic coupling leads to collective effects and super-Planckian thermal radiation excha…
Near-field heat transfer between graphene/hBN multilayers
Bo Zhao, Brahim Guizal, Zhuomin M. Zhang +2
We study the radiative heat transfer between multilayer structures made by a periodic repetition of a graphene sheet and a hexagonal boron nitride (hBN) slab. Surface plasmons in a…
Collective Near-Field Thermal Emission from Polaritonic Nanoparticle Arrays
Eric Tervo, Zhuomin Zhang, Baratunde Cola
The spectral characteristics of near-field thermal emission from nanoparticle arrays are explained by comparison to the dispersions for propagating modes. Using the coupled dipole…
